Latest Patents

John M Clarke holds a patent for an exhaust brake system. This system features a compact housing that includes an exhaust gas passage and a nonsymmetrical, rotatable restricter valve member. The design allows the restricter valve member to rotate from an open position, where its shield is parallel to the exhaust gas flow, to a closed position, where it is perpendicular to the flow. The unique design creates a gap between the restricter shield and the housing when closed, ensuring effective operation. The nonsymmetrical design also provides a weathervane effect, allowing the valve to return to the open position when disconnected from the actuator. This compact design facilitates direct mounting to engines or turbochargers, enhancing its practicality.
